Analog switches, multiplexers, and demultiplexers are essential components in any interface system as they help route and control signals within the system. The ADG738WBRUZ-REEL from Analog Devices is a single supply, low on-resistance multiplexer/demultiplexer designed to provide input/output insulation voltages of up to 5000 Vrms. The device features a CMOS logic level input/outputs, low on-resistance switching, and configurable logic levels to ensure data integrity. In this article, we\'ll discuss the application field and working principle of the ADG738WBRUZ-REEL.

Application Field

The ADG738WBRUZ-REEL is a single supply analog switch, multiplexer and demultiplexer that is used in various applications requiring signal switching, multiplexing and demultiplexing. It is commonly used in industrial, medical, consumer, and automotive control applications for signal routing in distributed control systems. It is also used in applications that require a high level of isolation, such as 3G and 4G base station designs. The device can be used in systems with multiple power supply voltages, such as those that require different voltages or those that require power supply float (switching between positive and negative supply voltages).

Working Principle

The ADG738WBRUZ-REEL is a single supply, low on-resistance multiplexer/demultiplexer designed to provide input/output insulation voltages of up to 5000 Vrms. The device features configurable logic levels, low on-resistance switching, and CMOS logic level input/outputs. It contains dual 4:1 multiplexers, a 4:1 demultiplexer, and 4 high voltage switches. The device has two logic inputs (S0, S1) and two enable inputs (EN1, EN2). The logic inputs are used to select which of the four sources to activate and which of the four destinations to connect. The enable inputs trigger the multiplexer. When enable inputs EN1 and EN2 are both high, the multiplexer is enabled. When there is an enable signal on either of the enable inputs, the multiplexer is disabled. The device also has four analog input lines, four analog output lines, and two power supply connections. When enabled, the device acts as a multiplexer, routing one of the four analog signals to the output. When disabled, the device acts as a demultiplexer, routing the input signal to one of the four outputs.

Conclusion

The ADG738WBRUZ-REEL is a single supply, low on-resistance multiplexer/demultiplexer designed to provide input/output insulation voltages of up to 5000 Vrms. It features configurable logic levels, low on-resistance switching, and CMOS logic level input/outputs. The device is used in various applications requiring signal switching, multiplexing, and demultiplexing and is commonly used in industrial, medical, consumer, and automotive control applications. The device is also used in applications that require a high level of isolation, such as 3G and 4G base station designs. With its configurable logic levels, low on-resistance switching, and CMOS logic level input/outputs, the ADG738WBRUZ-REEL is an ideal choice for routing signals in distributed control systems.
